Exploring chemical kinetics at home in times of pandemic: Following the bleaching of food dye allura red using a smartphone
(American Chemical Society, 2021-05-12)
In this communication, a remote experimental activity in chemical kinetics is described, taking into account the quantification based on the optical sensor of a smartphone. The objective pursued herein is to equip students ...
Characterization of two temperate lactobacillus paracasei bacteriophages: Morphology, kinetics and adsorption
(Karger, 2015-03)
Background/Aims: Adsorption and kinetic parameters, latent period, burst size and burst time, are characteristics of phage/host systems and can be affected by several environmental factors. As only few studies have focused ...
Kinetic Parameters for the Thermal Inactivation of Peroxidase and Lipoxygenase in Precooked Frozen Brassica Species
(Wiley Blackwell Publishing, Inc, 2017-06)
Thermal inactivation of peroxidase (POD) and lipoxygenase (LOX), both enzymes present in broccoli and Brussels sprouts, is required before freezing, to obtain high-quality precooked frozen vegetables. Rate constants of a ...
The application of different techniques to determine activated sludge kinetic parameters in a food industry wastewater
(Water Research Commission, 2004-04)
In the present work, a continuous-feed system under steady state conditions (classical method) and a respirometric technique based on oxygen consumption measurements, were used to compare microbial parameters using a ...
Net growth rate of continuum heterogeneous biofilms with inhibition kinetics
(Nature Publishing Group, 2018-12)
Biofilm systems can be modeled using a variety of analytical and numerical approaches, usually by making simplifying assumptions regarding biofilm heterogeneity and activity as well as effective diffusivity. Inhibition ...
Study of the Extraction Kinetics of Lithium by Leaching β-Spodumene with Hydrofluoric Acid
(Molecular Diversity Preservation International, 2016-09)
Parameters affecting the kinetics of the dissolution of β-spodumene with hydrofluoric acid have been investigated. The experimental tests were carried out in a closed vessel. The influence of several parameters, such as ...
Kinetic analysis and thermodynamics properties of air/steam gasification of agricultural waste
(Elsevier, 2020-03)
The air/steam gasification of wood sawdust (SD), plum and olive pits (PP, OP) bio-wastes was studied using macro-thermogravimetric analysis at three heating rates (5, 10, 15K/min). Three stages were identified during ...
Nonisothermal drying kinetics of biomass fuels by thermogravimetric analysis under oxidative and inert atmosphere
(Taylor & Francis, 2017-01-18)
In depth investigation of nonisothermal drying kinetic, the first stage of thermal decomposition was conducted using thermogravimetric analysis, to deepen the thermal processes’ knowledge. The studied biomass wastes were ...
Kinetic modeling of thermal degradation of color, Lycopene, and ascorbic acid in crushed tomato
(Springer, 2021-01-12)
The kinetics of the thermal degradation of color (L*, a*, and b* coordinates), lycopene (L), and L-ascorbic acid (AA) in crushed tomato were studied over a temperature range of 70 to 100 °C. These results showed that the ...
